取消查询应该怎么写，查询功能我已经成功了！

<form action="?" method="get" name="searchForm">
  <tr>
    <td height="22" align="right">客户名称：<input name="company" type="text" class="input1" value="<%=request("company")%>" size="25">
      联系人：<input name="CustomerName" type="text" class="input1" value="<%=request("CustomerName")%>" size="15">
      客户类型：<select name="CustomerTypeName" class="input1"><option value="">-请选择-</option>
            <%=Options("RC_NoCustomerType","CustomerTypeName","CustomerTypeName","",CustomerTypeName)%>
          </select>         
      <input name="searchSubmit" type="submit" class="submit" value="查 询">
      <input type="hidden" name="moduleid" value="<%=moduleid%>"></td>
  </tr></form>
各位高手，请问取消查询怎么写呀，我已经写好了查询，可以按客户名称或联系人或客户类型查询的！
